Summary: The mid-level series is a network of phreatic passages formed in a bed around 15m lower than the Near End series. The trunk passage of Wolpertinger Way slopes down from the bottom of Thread Pitch towards an area of interconnecting passages around the foot of Pendulum Pitch. From here one can descend into the Ariston Series, or follow passages into the Millennium Dome area, or via No Pain No Gain to the northern parts of the cave.
Thread Pitch and Stitch This from the Near End series land at the top of a large 6-8m diameter phreatic passage, Wolpertinger Way. This heads downhill, past some ice formations on the left hand side, for 35m to a junction. To the left Recycled Rabbit leads off, which was for a long time not noted. Straight ahead is a steep gully leading to a 6.5m diameter circular shaft with aven above - You're So Veined. There is a traverse round the right hand side of the gully on an increasingly narrow ledge.
To the right from the top of the gully, passing over a hole in the floor through dangerous boulders [C1999-204-09 C], reaches a junction. Right is a passage, which quickly chokes, straight ahead leads into 110 A Day, whilst left is the main route.
More sandy crawling leads to a crossroads, where left leads to the ledge overlooking the pitch, and right is a short crawl leading to the main passage part of the way down Pendulum Pitch, the easiest route to the White Elephant Series. Straight ahead leads to a further junction. Left is a ledge, from which one can descend onto a bridge of boulders between You're So Veined and Pot-U-Like, the current trade route into the Ariston Series. Alternatively, traversing along the ledge leads towards Bunny's Bowel.
Right at the junction is a short passage to a blind pit. Traversing around this to the right gives an alternative route to Pendulum Pitch. Traversing around to the left leads a rift that leads initially upwards, where a passage leads of to the right; continuing along down the rift leads to an undescended pitch [C2001-204-67 B]. A passage on the opposite side of the pitch can be accessed from the top of You're So Veined. The passage leading of to the right of the rift quickly enters a small chamber. To the left leads to the undescended pitch [C2001-204-67 B]; straight on leads to a junction, with both ways on being too tight. To right from the small chamber leads to the passage between Pendulum Pitch the Millennium Dome area.
Traversing towards the right at the head of You're So Veined leads to a boulder floored passage. A window looks out to the left to the head of an undescended pitch [C2001-204-66 C]. Carrying on leads to the previously described undescended pitch [C2001-204-67 B]; looking across this passages are visible, one of which is the link between Wolpertinger Way and the Pendulum Pitch route. To the left a climb leads to a short passage to Bunny's Bowel, a small chamber. A passage doubling back leads underneath the previous passage to the undescended pitch [C2001-204-67 B]. In Bunny's Bowel, a climb to the right leads to a drop into the passage from Pendulum Pitch to Millennium Dome. A window to the right leads to a 3m climb (rigged with a handline) to a muddy chamber with a 3m deep hole in the floor, with ways on that were too tight. Back in Bunny's Bowel, to the left the passage goes past an undescended 8m pitch [C2001-204-65 C], then finishes in a mud choke.
Near the southern end of Wolpertinger Way, on the left of the passage as one descends, is a small low crawling-size passage leading off at right angles. The passage continues for 65m, climbing slightly and remaining approximately the same diameter throughout its length. The passage ends too tight but on the right there is an impassable (at present) connection with a moderately sized chamber - but the use of plug and feather may enlarge the connection to allow passage. [C2001-204-73 C]
110 A Day is a long, dusty passage which varies between stooping and crawling for 110m. Immediately after the start is a sharp right hand bend with a crawl straight ahead to 110 Bidet. About halfway along is a crossroads, where low passages lead off to the left to 110 Bidet and to the right [C1999-204-13 C]. At the terminus reached in 1999, the passage splits into two. Each branch immediately becomes tight, but could be pushed further with a little determination and effort [C1999-204-14 C and C1999-204-15 C]. In the left hand branch, just before the passage becomes tighter, is a pitch of perhaps 20m; all the ways on at the base of this are too tight.
110 Bidet is a stooping size passage which runs parallel to 110 A Day. It can be accessed via a crawl about 1m up that carries straight on from where 110 A Day starts with a sharp right hand turn. The crawl emerges into larger passage; to the left after 5m is Pendulum Pitch. Going right leads to a hole in the floor among boulders, Marble Run. To the left here is a low passage leading to No Pain No Gain, whilst 110 Bidet carries straight on. Continuing on, the passage turns right, followed shortly by a crossroads with a crawly passage. To the right is a dead end; to the left is Upwards at 45°. Straight on emerges into 110 A Day about half way along its length.
Martin 2002-3: [C2002-204-09 C] [C2002-204-10 C] [C2002-204-11 C] [C2002-204-12 B] [C2002-204-13 B] [C2002-204-14 C] [C2002-204-15 B]
Marble Run runs along a fault line that created a small passable phreatic tube, which has subsequently been intersected by a tight rifty stream way. 20m along the rift bears to the right and is too tight to pass, whilst the phreatic passage continues on to a small chamber. Here the passage doubles back over itself to continue above the original passage. The passage does this once more to end in an earth blockage.
Pendulum Pitch is in a large rift. The first section is a loose boulder slope (care required) to a rebelay, then a descent of 23m via a deviation off the far wall below a large wedged boulder. There may be a passage on the far side of the rift accessible with difficulty from this boulder [C1999-204-17 C]. From the base of the pitch, two rift passages lead off which very quickly become too tight.
The main route on is reached by swinging off after 16m into a 6m wide passage. Two passages in the left hand wall are quickly encountered. The first quickly becomes too tight, the second is a short crawl leading into the network of sandy crawls at the bottom of Wolpertinger Way, and is the best route from here to the Ariston Series. Continuing down the main passage, passing either side of a huge boulder, reaches a blind pit in the floor, with two ways on.
A loose and slightly precarious traverse round the blind pit leads to a short passage on the left, emerging at the head of You're So Veined. A rift visible at the opposite side of the pit has an audible connection to You're so Veined.
To the right at the blind pit is a draughting phreatic tube leading towards the Millennium Dome area.
